The Alliance Defense Fund, a conservative Christian organization known for taking up causes from fighting pornography to religious discrimination in the workplace, is calling for pastors to give sermons about specific candidates on Sept. 28.

During election seasons, many clergy, both liberal and conservative, have stepped up their political rhetoric but stayed in the safe zone of moral issues. Some told the congregation who they are voting for, arguing legally they are still within their rights because they are speaking for themselves and not as the church’s spiritual leader.

Critics believe this tactic is a front to mask an actual church endorsement.
